Authorities did not say how Christal Dawn Wiggins, 29, died, but said her death could be linked to those of Jackie Bradley, a homeless woman found March 31, and Carrie Ann Caughey, a teen runaway discovered Thursday.

Police began searching for Wiggins on Sunday, a day after her mother reported her missing. She was found Monday.

Wiggins, who would have turned 30 Tuesday, was a prostitute with a criminal record, police and court records show. She was in the St. Lucie County Jail two weeks ago on drug charges and driving offenses.

Bradley and Caughey also led troubled lives, said Martin County Sheriff's Sgt. Jenell Atlas.

During the weekend, the sheriff's office began visiting homeless camps, warning people about the slayings and hoping somebody might know something, Atlas said.
